Solution

1. Preparation

Ensure the vehicle is parked on a level surface and turn the ignition to the "ON" position without starting the engine.
Check and adjust the tire pressures of all tires, including the spare, to the manufacturer’s specifications (found on the driver’s side door jamb).

2. Reset the Tire Pressure Monitor System

Locate the tire pressure reset button, typically found beneath the steering column or on the lower dashboard panel.
Press and hold the reset button until the tire pressure monitor light blinks three times, then release the button.
Start the vehicle and allow it to run for a few minutes to ensure the system can recalibrate.

3. Confirm Reset

Drive the vehicle for a short distance (approximately 10-15 minutes at speeds above 25 mph).
Observe if the tire pressure monitor light remains off; if it turns off, the reset was successful.
